Explanation:
i alr explained
Comets are objects in the space that is composed mainly of dust and ice. While approaching the sun, a tail grows. Comets have nucleus which represents the hard rock object. As it nears the sun, it heats up the comet causing it to vaporize. Meteors, on the other hand, are what we call "shooting stars". They are interplanetary dusts that burn up as it approaches the Earth's atmosphere.
I think B. is the correct answer i hope i helped
Reduction is the process by which eletrons are gained by an atom.
Answer:
Option B. 4.25×10¯¹⁹ J
Explanation:
From the question given above, the following data were obtained:
Frequency (f) = 6.42×10¹⁴ Hz
Energy (E) =?
Energy and frequency are related by the following equation:
Energy (E) = Planck's constant (h) × frequency (f)
E = hf
With the above formula, we can obtain the energy of the photon as follow:
Frequency (f) = 6.42×10¹⁴ Hz
Planck's constant (h) = 6.63×10¯³⁴ Js
Energy (E) =?
E = hf
E = 6.63×10¯³⁴ × 6.42×10¹⁴
E = 4.25×10¯¹⁹ J
Thus, the energy of the photon is 4.25×10¯¹⁹ J
